If I move my TX stick to full output, the servo ofcourse moves full travel. But at the end of full travel it moves back a little bit. As if it overshootes the "stop" and then moves back.
The servo does that in both directions, and only at full movement of the TX stick. And Im sure its the servo, because i have two servos mixed together for my delta, and only one has this problem.

Why??? What´s wrong with it.?

Hope you understand what i mean, as my explenation might not be too good.

Just sounds like 'lag' to me. The little motor is spinning like crazy to get the arm there as quickly as possible, but it's overshooting a little, so it backs up to compensate. You probably won't (shouldn't) be using 100% of the travel anyway, so it shouldn't be an issue.
Just make sure there's no play in the arm in any position.

What servo brand is it? Hitech??

I've heard of something about Hitech servos from the LHS.. But I'm not suggesting that's the problem.
